I am out and about right now, but I purchased the Aviator edition of 2024 because I have spent so much money buying additional aircraft over the years. I know I have at least one 737 but I am not sure... it might have been something that I purchased previously. I do not believe that I have an American Airlines livery. The passengers can be added to the weight and balance, but I am not sure if there is an add-on to make them visible in the simulator...
PMDG makes the best payware 737 by far in my opinion. The fully functional FMC is way cool and fun to setup.
